Abstract

An automotive lighting element has a lower surface with a plurality of ridges and grooves. Those ridges and grooves are reflectorized so that light emitted by a light source in the lighting element will be reflected back into other portions of the reflector rather than out of the lighting element with a large upward vertical component.
